Remote fishery management system

ABSTRACT

A system to monitor compliance with fishery management regulations by recording time and location stamped video of a catch. The system utilizes battery powered miniature camera/DVR modules capable of being mounted virtually anywhere on a fishing vessel. The cameras are activated by software triggers using motion and changes in hydraulic pressure to avoid the capture of unwanted video and unnecessarily draining the battery. A method of analyzing the video data to ascertain species, size, and mass is also disclosed.

TECHNICAL FIELD

The device of the present application relates generally to audio-visualelectronics. More specifically, the device of the present applicationrelates to a device and method which permits greater miniaturization ofthe camera while permitting the recording of high definition video. Morespecifically, the device of the present application relates to a deviceand method which permits the recording of video and GPS data for thepurpose of catch verification in remote fishery management.

BACKGROUND

Digital cameras have undergone increasing miniaturization and they haveenabled an increasing variety of opportunities for low-resolutionhands-free photography and videography. Digital videography has beenfurthered by the use of improved data compression, higher bandwidth dualpurpose cables and better audio-video interfaces, e.g. DVI, HDMI, IEEE1394, and DisplayPort. However, the transfer of increasinglyhigher-definition video requires a greater bitrate than conventionalcoaxial cable can provide because of the use of significantly morepixels per image and a higher frame rate. The ability to transfer largeamounts of data at high speeds has been a limiting factor to the use ofminiature cameras since data storage must be remote from the camera toachieve the smallest configurations. Signal attenuation is also asignificant barrier which limits the effective length of the audio-videocable.

HDMI cable can be manufactured to Category 1 specifications easily andinexpensively by using 28 AWG conductors which have diameters of 0.0126in, i.e. 0.321 mm. Higher quality HDMI cables can be manufactured toCategory 2 specifications and utilize 24 AWG conductors which havediameters of 0.0201 in, i.e. 0.511 mm. Several versions of the HDMIspecification have been released with HDMI 2.0 being the most recentlyreleased version. HDMI versions 1.3 and 1.4 are much more common.

The effective length of an audio-video cable is limited by the bandwidthof the cable and signal attenuation. When an audio-video cable is usedto transfer data in real-time with no buffer at the camera the effectivelength is reduced even further.

Information about the health of off-shore fisheries is general anduncertain about fish stocks and the condition of fishing grounds as awhole, about the health and abundance (or lack of it) of the manycommercial varieties, of their location in abundance or deficit, oftheir migration patterns, and of their breeding patterns, seasons, andefficiencies. The gathering of most of this vital information currentlyfalls almost exclusively to a few public inspectors and privateresearchers.

In jurisdictions that support and control the fishing industry,governments attempt to provide, within budgetary constraints, theinspection of and reporting on fishing operations and on the conditionof fishing grounds and of fish stocks through variously named“departments of marine resources.” From time to time, this informationmay be augmented by the efforts of non-governmental fishingorganizations, e.g., the FAO, which is part of the United Nations, andby the necessarily narrow interests of academic or institutionalresearchers.

Currently, the limited data collected by these means, and the analysisof such data, form the sole basis of governmental regulation of thefishing industry. The trouble is that, relative to the size of theindustry and the volume of information necessary to form the basis ofvalid judgments, the number of persons collecting such information issmall, making the accumulation of a statistically significant volume offishery-related data difficult or, arguably, impossible.

Management of commercial and recreational fisheries has long been apoint of conflict between governments and harvesters. This conflict isdue to the common pool nature of the resource and the competinginterests of various user groups that rely on the resource for food,income, and recreational opportunities. Policy choices for themanagement of aquatic food resources are typically multidimensional, andinvolve a variety of regulatory instruments to control the harvesting soas to maintain a healthy population. Because fishery management plansare usually tied to the status of fish stocks, governments typicallymonitor and assess changes in the fish biomass on a regular basis.

Ensuring compliance with these fishery management plans is anincreasingly difficult process, especially for off-shore fisheries, andcompliance is an increasingly expensive process for the commercialharvester. Regulations intended to promote sustainable exploitationimpact the species harvested, the physical attributes of the catch, thequantity of the catch, methods used in the catch, and efforts tominimize harm to protected species.

The primary limitations in fishery management plan development andcompliance are the absence of quality data and the expense of shipboardobservers. Fishery management decisions are often based on populationmodels, but the models need quality data to be effective. Scientists,fishery managers, and commercial harvesters would be better served bythe collection of more accurate data and through the elimination ofshipboard observers. Additionally, the absence of cost effectiveelectronic monitoring systems harm the commercial harvester becausevarious programs improve the profitability of commercial fishing throughincentives tied to the use of on-board electronic monitoring.

There is a need for improved methods of gathering information on bothkept and discarded commercially important species from a catch.Management decisions are currently based on information largely gatheredby established federal surveys and observer programs which are costly tomaintain. Under many past management plans, fisheries were managed by aDAS (Days at Sea) system. The DAS system allocates a certain number offishing days to each vessel over the course of a year. When a vesseluses up its allocation of days, it can either cease operations until thefollowing year or purchase additional fishing days from idle vessels.The DAS management strategy has come under scrutiny in recent years dueto safety concerns and other issues.

Ideally, each catch would be monitored, but this is an expensive andtime-consuming process requiring significant man-hours. The recording ofvideo and the coordinates of each catch greatly improves compliance withfishery management plans and provides a record that protects bothfishery populations and those involved in commercial fishing.

Existing systems cannot be used on small vessels as they are essentiallya “convenience store security system” hardwired into a boat. They havelarge footprints because they use multiple domed security camerashardwired into the vessel in communication with a central computerinstalled in the wheelhouse. These existing systems have largefootprints that take up precious space, use expensive components notamenable to relocation on a vessel or redeployment to another vessel,and require expensive maintenance and repair.

On-board observers are typically the only independent data collectionsource for some types of at-sea information required by fisheries, suchas bycatch and catch composition data. Creel surveys, trip reports, andother data obtained directly from fishermen can have some dependent biasassociated with it. Fisheries-dependent information is critical for theeffective execution of fishery management plans, but on-board observerstake up space that could be used for an additional crew member and areexpensive. Recent data from NOAA suggests that electronic monitoringwith currently available technologies is approximately ⅓ the cost ofon-board observers.

SUMMARY

The present application discloses a miniature digital camera systemusing a HDMI audio-video cable to transfer video data as it is collectedto an audio-visual data recording device, i.e. DVR (digital videorecorder) tethered to the end of a data cable. The digital cameracollects high-definition (HD) video and feeds it directly to a DVR inreal-time. Normally, the HDMI audio-video cable would not be able toprovide the throughput needed at a cable length in excess of a fewcentimeters due to signal attenuation. While the applicationpredominantly discussed throughout this disclosure relates to HD videorecording, nothing in this disclosure should be read as limiting thedata collected to video within the spectrum visible to humans as it isanticipated that data of interest at other wavelengths, e.g. infrared,ultraviolet, ultrasound, etc. . . . , could also be recorded in additionto specific wavelengths, processed signals, and low light visualization.

A method of data conversion is disclosed herein which enables increasedHDMI tether length of the audio-visual cable for placement of the DVRseveral feet from the digital camera. A method of connecting the HDMIaudio-visual cable to the printed circuit board of the digital camera soas to minimize the camera size is also described.

Various embodiments of miniature camera housings and mounting means aredescribed herein which facilitate the use of the miniature camera systemin various applications for broadcast and training, e.g. horse racing,football, and hunting.

A lens protection system and method for use which maintains the lens ina substantially clean state so as to not allow dirt and otherenvironmental contaminants to interfere with the image to be recorded isalso described herein. In a preferred embodiment of the system, aplurality of removable transparent lens covers are arranged to cover acamera lens. A further embodiment is described which permits recordingvideo from the perspective of a jockey. A still further embodiment isdisclosed which relates to wirelessly transmitting the video and/oraudio recorded.

The present application discloses a system to monitor commercialfishing. The system utilizes a control system to integrate digitalcamera, global positioning satellite (“GPS”) system date, and time/datedata to mark the recorded video with temporal and location data. Thepurpose of the system is to monitor commercial fishing for compliancewith laws and regulations governing open-sea fisheries and to facilitatethe management of these fisheries through the collection and analysis ofcatch data captured by HD video. The data collected can assist in themonitoring and management of invasive species. The recorded video canalso be supplemented by additional inputs, e.g. hydraulic pressure, netwinch motor activation, temperature, light, motion, sound, andultrasound, in addition to monitoring other spectral wavelengths suchinfrared and ultraviolet.

The system can be configured to actuate manually or automatically. In anautomatic actuation configuration, the system utilizes configurablesoftware triggers programmed to utilize sensor data provided via theadditional inputs from a plurality of available data channels to turncameras on an off and to select appropriate cameras.

The video data can be analyzed to determine species, size, mass, andhealth of the catch. Species can be determined by pattern recognition ofanatomical features and striations. Size can be calculated relative to amarker of known dimension. Mass can be closely approximated based onsize and species determinations. Health can be evaluated by evaluatingthe foregoing variables and analyzing motion. Examination of the catchunder different spectral wavelengths may also provide supplemental datato support the previously discussed determinations.

The present apparatus recognizes and addresses long-felt needs andprovides utility in meeting those needs in its various possibleembodiments. To one of skill in this art who has the benefits of thisdisclosure's teachings, other and further objects and advantages will beclear, as well as others inherent therein. The disclosures herein arenot intended to limit the scope of the invention, merely to providecontext with which to understand the patent claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A high definition miniature camera system 100 is disclosed herein inaccordance with FIG. 1. A miniature camera 90 as depicted in FIG. 2 isfurther disclosed herein. This assembly incorporates a video sensor 18integrated onto a camera PCB 10, i.e. printed circuit board, preferablya circuit board capable of supporting high speed serial communicationlines. The PCB 10 is affixed within a lens housing 35 having a lens 60or lenses 60 which is affixed over the video sensor 18. The PCB 10 isreceived within the lens housing 35. In a preferred embodiment, the lenshousing 35 is a planar panel having a distal lens support surface 32 anda proximal lens support surface 34 from which the lens housing 35extends in a substantially perpendicular orientation to the proximallens support surface 34. The lens housing 35 is affixed to the PCB 10across the distal lens support surface 32 with the video sensor 18oriented toward the distal lens support surface 32 with the lens housing35 substantially centered above the video sensor 18.

As depicted in FIG. 2, the PCB 10 and lens housing 35 combine to formthe camera module 40 and are contained within a camera module housing70. The camera module housing 70 is preferably constructed from at leasttwo parts which assemble together to encase and secure the PCB 10 andlens housing 35. The proximal camera module casing 50 preferablypossesses, in part, the lens housing 35, dowel receptacles 55, lenshousing port 62 and proximal camera module recess 51 into which the lenshousing 35 with the installed PCB 10 are received. The distal cameramodule casing 41 preferably possesses, in part, the distal camera modulerecess 47 and dowels 43. To assemble, the camera module 40 is insertedinto the proximal camera module recess 51 in the proximal camera modulecasing interior surface 53 with the lens housing 35 received into thelens housing port 62.

Mobile phone and smart device camera and microphone technology isbelieved to be suitably small and be sufficiently power efficient to beof use in this configuration, however, in a preferred embodiment, a highdefinition video sensor 18 equipped with wide angle lens 60 having aresolution of at least 3 megapixels, more preferably at least 4megapixels, and most preferably at least 5 megapixels is integrated ontothe PCB 10 beneath the lens housing 35.

The distal camera module casing 40, as depicted in FIG. 2, is alignedwith and affixed to the proximal camera module casing 50 by alignmentmeans 43, e.g. dowels 43. The camera module housing 70 may be furthersealed with the application of an adhesive along the camera modulehousing 70 joint 66. A preferred embodiment of the alignment means 43utilizes dowels 43 protruding from the of the distal camera modulecasing 40. The dowels 43 of the distal camera module casing 40 arereceived into dowel receptacles 55 within the proximal camera modulecasing 50 so as to join the proximal and distal camera module casings32, 40. The proximal and distal camera module casings 32, 40 are securedin their joined orientation and sealed. In a further preferredembodiment, the lens 60 is seated against the lens housing 35 to inhibitthe introduction of moisture and contaminants into the camera 90. In afurther embodiment, a seal 66 is placed between the lens 60 and lenshousing 35 to further weatherproof the camera 90. In an alternativeembodiment, the lens housing 35 possesses an interior annular groove 65about the lens housing interior surface 67 to further improve theweather resistance of the camera 90 by inhibiting the introduction ofwater and environmental contaminants into the camera module housing 70.

The camera module housing 70 casings 32, 40 are preferably constructedof plastic, preferably molded from a deformable material such as athermoplastic, e.g. acrylonitrile butadiene styrene (ABS). The casings32, 40 may be created from a mold or from a three-dimensional printer.Plastic is a preferred material due to the cost of materials andmanufacturing as well as its low mass and rigid nature. The cameramodule housing 70 may further possess a camera mounting means 130 tofacilitate the placement and affixation of the camera 90 to a desiredlocation. The camera mounting means 130 may be affixed to the cameramodule housing 70 or it may be integrated into one or more camerahousing casings 32, 40. Non-limiting examples of camera mounting means130 include tensioned clips, mounting arms with hardware attachmentmeans (e.g. screws) receiving holes, and ring clamps.

As depicted in FIG. 1, in a preferred embodiment, an audio-visual cable140 is used to transfer data from the camera PCB 10 to a remoteaudio-visual data recording device 200, i.e. data storage device 200,e.g. a DVR 200. A HD video sensor 18 on the PCB 10 converts imagesobtained through the lens 60 into data which are associated withspecific pixels on each captured image frame. Since the stream of videodata is continuous, discrete frames are captured sequentially at a ratemeasured in frames per second, i.e. fps. Each pixel contains data,therefore the greater the resolution and the greater the number ofpixels, the greater the amount of data collected and transferred.Additionally, the greater the image fps, the greater the number offrames are recorded and therefore an increasingly greater amount of datais collected and transferred. The data from the video sensor 18 istransmitted in a parallel communications protocol. Protocols forparallel transmission, such as those used for computer ports, have beenstandardized by ANSI.

Parallel communications protocol is a method of conveying multiplebinary digits, i.e. bits, simultaneously. It contrasts with serialcommunication protocol, which conveys only a single bit at a time.Interference between parallel lines, i.e. crosstalk worsens withincreasingly longer lengths required for the parallel communication linkalong the audio-visual cable 140. Crosstalk, e.g. undesired capacitive,inductive, or conductive coupling, is a phenomenon by which a signaltransmitted on one channel creates an undesired effect in anotherchannel. The ratio of the power in a disturbing channel or circuit tothe induced power in the disturbed channel circuit is crosstalk couplingand is expressed in units of dB when describing crosstalk coupling loss,i.e. signal loss. This restricts the effective length of a parallel dataconnection for use with this application to about 3 centimeters when ameter or more is typically necessary to remove the media recorder 200from the immediate vicinity of the camera 90.

To avoid the significant signal interference and/or signal lossencountered while transmitting parallel communications data, theparallel data is converted, as described in FIG. 6, to serial data byintegrated circuitry 37 affixed to the camera PCB 10. The integratedcircuitry 37, e.g. a microcontroller, microprocessor, or functionalequivalent, may be separate componentry affixed to the camera PCB 10 ormay be the video sensor 18. Parallel-to-serial conversion converts astream of multiple data elements, received simultaneously, into a streamof data elements transmitted in time sequence, i.e. one at a time.Recent improvements in serial communications have resulted in serialcomputer buses becoming more common as improved signal integrity,transmission speeds, and simplicity have begun to outweigh itsdisadvantages relative to parallel communications, e.g. speed, clockskew, and interconnect density.

As depicted in FIG. 2, in order to transmit significant amounts of videodata to a remote media recorder 90, a standard mini-HDMI cable 140 isrepurposed and the conductors 131 therein are used as separate lowvoltage differential serial communication lines to obtain the necessarythroughput without sacrificing the signal. The serialized data can betransmitted over a repurposed mini-HDMI cable 140 for at least 54 in,1.3716 m, without significant signal interference or loss. Video sensors18 with higher resolution capacity require an audio-visual cable 140with more conductors 131 to transmit the data at a sufficient bitrate tocapture all of the data.

In a preferred embodiment, a CMOS, i.e. a complementarymetal-oxide-semiconductor, imaging chip is utilized as the video sensor18 on the PCB 10. CMOS is a type of active pixel sensor made using theCMOS semiconductor process. The video sensor 18 converts the receivedlight energy to a voltage. In a CMOS video sensor 18, each pixel has itsown charge-to-voltage conversion, and the sensor 15 often also includesamplifiers, noise correction, and digitization circuits, so that chipoutputs are digital bits.

In a further preferred embodiment, a 5 megapixel (MP) CMOS sensor 15with a dynamic range of about 70 dB is integrated with the PCB 10 toprovide responsivity of less than 2 microvolts/lux-s. Dynamic range isthe ratio of a pixel's saturation level to its signal threshold.Responsivity is the amount of signal the sensor 15 delivers per unit ofinput optical energy. This generates approximately 2,353 MB/s of data.Frame rates of 30 fps are utilized which generates 1,176 MB/s of data,although 60 fps is possible. The mini-HDMI audio-video cable 140 isrepurposed to provide eight serial channels using sixteen conductors131. Using 8 channels, an effective communication speed of approximately147 MHz at 30 fps is achieved using a standard LVDS, i.e. low-voltagedifferential signaling, serial communications protocol. Alternativeembodiments employ HiSPi, Four-Lane MIPI, or other available serialcommunications protocols.

In a still further embodiment, the video sensor 18 is a module that maybe removed and interchanged with other video sensors that sense light atdifferent wavelengths and/or levels, e.g. non-visible wavelengths. In apreferred embodiment, a low light video sensor can be removably affixedwithin the camera module housing 70. In yet a further embodiment, aninfrared sensor can be removably affixed within the camera modulehousing 70. In a still further embodiment, an ultraviolet sensor can beremovably affixed within the camera housing 70. Moreover, the lens mayalso be interchanged to provide for different focal lengths, filters, oreven a wide-angle lens.

To achieve optimal miniaturization of the camera 90, the audio-videocable 140 is hard wired directly to the PCB 10 by soldering conductors131 to terminals on the PCB solder side 14. The audio-video cableconductors 131 are soldered directly to the PCB solder side 14,therefore the PCB 10 can be constructed substantially smaller than a PCB10 having a conventional audio-video cable 140 connection using machinesoldering methods, e.g. incorporating a standard male or female HDMIconnector onto a flange on the side of the PCB 10 for the wire solderpads. As a result the camera 90 can be further miniaturized through theelimination of the standard male or female connectors on the PCB 10.Additionally, the absence of a bulky connector allows the for thearbitrary orientation of the audio-video cable 140 as it exits thecamera module housing 70, providing flexibility in camera module housing70 design.

After the audio-video cable 140 exits the camera module housing 70through the audio-video cable port 68, the audio-visual cable 140 isretained by the cord guide 57. The cord guide 57 is preferably affixedto or integrated onto the camera module housing 70. The cord guide 57secures the audio-video cable 140 to the camera module housing 70 sothat the soldered connections 36 affixing the audio-video cable 140 tothe PCB 10 will not be damaged and disconnected.

The CMOS video sensor 18 chip compresses the video into a compressedvideo file, preferably for temporary storage in flash memory prior torecording the data. Preferably the digital video is compressed into astandard format, e.g. mp4, avi, etc. . . . , and subsequentlytransmitted via an audio-video cable 140 to a media recorder 90. In ayet further preferred embodiment, the video is transmitted wirelessly bya transmitter 189 or transponder 189.

In a preferred embodiment, Bluetooth is used as a means of wirelesscommunication. All modern mobile telephones are Bluetooth enabled andhave that protocol factory installed, as do most personal electronicdevices; therefore a Bluetooth based implementation provides a proventechnology which would be economical and cost effective. Connectionsbetween Bluetooth enabled electronic devices allow these devices tocommunicate wirelessly through short-range, ad hoc networks known aspiconets. Piconets may be established dynamically and automatically asBluetooth enabled devices enter and leave radio proximity. Bluetoothtechnology operates in the unlicensed industrial, scientific and medical(ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequencyhopping with Gaussian frequency shift keying (GFSK), differentialquadrature phase shift keying (DQPSK), or eight-phaseshift differentialphase-shift keying (8DPSK) modulation. The basic data gross rate is 1Mbit/s for GFSK, 2 MB/s for DQPSK, and 3 MB/s for 8DPSK.

The 2.4 GHz ISM band is available and unlicensed in most countries.Ideally, a Bluetooth transmitter used in the present system will be aclass 1 radio, having a range of up to approximately 200 meters (roughly984 feet). In a preferred embodiment, the range could be adjusted byoptimizing the power to the associated Bluetooth transponder. Thefollowing table identifies the power scheme for each class of Bluetoothradio.

Serialized data from the video sensor 18 on the camera PCB 10 istransmitted to a remote video chip 153 for serial-to-parallel conversionand subsequent compression. The remote video chip 153 is housed on a DVRPCB 171, i.e. preferably a circuit board capable of supporting highspeed serial communication lines, in the DVR housing 174. As previouslystated, the DVR 200 can be located as much as 54 inches, i.e. 1.37meters, from the camera 90 due to the serialization of the data. Havingthe remote video chip 153 compress the data remotely allows for asmaller camera 90 footprint. Conventional miniature cameras use parallelcommunications and require the video chip 15 responsible for compressionto be located no more than 2-3 inches, i.e. 5-8 cm, from thephoto-detector 16 on the PCB 10.

After de-serialization of the data and subsequent compression, the datais stored onto computer readable media 97, e.g. micro-SD card, mini-SDcard, SD-card, solid-state drive, etc. . . . , for wired transfer via ahardware communications port, e.g. micro-USB, or wireless transfer by atransmitter 189. In a preferred embodiment, high speed micro-SDHC ormore preferably micro-SDXC format cards 97 having read/write rates of 25MB/s or higher are used. In an alternative embodiment, an embedded SDcard 97 may be used. Preferably, the computer readable media 97 isremovable for physical transfer to another device for use. In apreferred embodiment, a female mini-HDMI connector 159 is integratedonto the DVR PCB to receive the repurposed HDMI audio-visual cable 140and male mini-HDMI connector 157. A female micro-USB connector 162 isintegrated into the DVR PCB for wired transfer of the data from thecomputer readable media 97. A removable computer readable mediareader/writer 165, as depicted in FIG. 5, permits the user to removablyinsert a media card 167 into the DVR housing 174 and is connected to theDVR PCB 171 to receive the compressed video output from the compressionvideo chip 92. A microphone jack 156, preferably a 2.5 mm audio jack156, is integrated into the DVR housing 174 and connected to integratedcircuitry on the DVR PCB 171 to format and compress audio data from anexternal microphone 137 and transfer it to the computer readable media97. The mini-DVR further possesses a power button 185 to actuate a powerswitch 187.

As depicted in FIGS. 3-5, the DVR housing 174 is preferably a multi-partassembly of at least two parts, the DVR casing 180 and the DVR cover186. The DVR PCB 171, and connectors 159, 162 reside in the DVR casing180 and are powered by a direct current power source 134, i.e. batteries134, stored between the DVR PCB 171 and the DVR casing interior surface177. The batteries 134 may be accessed through a removably attachedbattery access panel 184 on the DVR casing exterior surface 183.

The DVR housing 174 is preferably removably attached to the wearer ofthe miniature camera 90 by a wearable DVR harness 250. The harness 250may be affixed wherever it may be conveniently worn. In a preferredembodiment, the harness 250 receives the DVR housing 174 which itsecures in a snap-fit arrangement with the tensioned harness arms 245sliding about the DVR housing 174 to retain the DVR 200 in a frictionfit arrangement. In a still further preferred embodiment, the harness250 possesses strap ports 230 to receive a fixed or adjustable strap 220or may receive the belt of the wearer. In a further embodiment, theharness 250 is equipped with a harness mount 240, e.g. tensioned harnessclip 240 which permits it to be slid onto an object and retained in afriction-fit arrangement. The DVR housing 174 further possesses amicrophone clip 247.

In an additional embodiment, as depicted in FIG. 13, the distal cameramodule casing 40 detachably mates with a camera mount 130. In apreferred embodiment, the camera housing 50 and camera mount 130 mate ina key-keyway arrangement. In a further preferred embodiment, the distalcamera module casing 40 possesses a slotted keyway 92 that is integratedwith the camera module housing 70 that is oriented substantiallyperpendicularly to the camera mount face 116 and parallel to axis alongthe length of the lens housing 35 of the camera 90. The key 98 issubstantially parallel to the camera mount face 116 and connected by akey support arm 104.

The keyway 92 is configured to descend onto they key 98 so that theexterior surface of the distal camera module casing 40 is substantiallyparallel with the key 98 and the camera mount face 116. The keyway 92possesses a key support arm channel 107 in the distal keyway wall 95 topermit the key 98 to traverse the keyway 92 without being hindered bythe keyway 92 until the key support arm channel 107 terminates at thekey stop 101. The key support arm channel 107 acts to help guide the key98 through the keyway 92 and secures its orientation so as to inhibitrotation. In a still further preferred embodiment, the key 98 is securedin the keyway 92 by a tensioned key stop tab 110 that is displaced bythe key 98 as it enters the keyway 92 and reengages once the key bottom113 of the key 98 passes the tensioned key stop tab 110 passes by and isno longer displaced. Removal of the key 98 must first be initiated bydepressing the tensioned key stop tab 110 to permit the key 98 to slideover it and down the keyway 92. In a further embodiment, they key 98 isT-shaped when viewed along its vertical axis, with the key support arm104 forming the figurative downward stem of the letter T and the keyway92 designed to receive and restrain the crossbar of the letter “T” asthe key 98 while possessing a key arm support channel 107 to permit thesupport arm to pass through the distal keyway wall 95.

In a still further embodiment, the angularrelationship between the support mount 119 and the key mount 122 ismodified by movement along an adjustable mount hinge 125.

Applications

Televised horse racing is a growing industry in the United States,spurred by progress in HD television broadcasting and the virtuallycomplete replacement of traditional antenna-to-antenna signalbroadcasting with satellite and digital cable transmissions. One populartrend in the industry is wagering on random rebroadcasts of old races.Previous industry attempts at capturing video from the jockey'sperspective met with significant failure due not only to camera size andvideo quality, but also with limitations created by dirt adhering to thecamera lens mid-race. Jockeys traditionally wear multiple sets of nestedgoggles 285 and shed them during the race as their vision becomesobscured from dirt kicked up by surrounding horses. Since the course istypically damp from being sprayed with water to inhibit dust formation,the dirt tends to adhere to the surface of the goggles 285 and canobscure the jockey's vision and the lens 60 of any camera worn in therace by the jockey. Moreover, some constituents in new synthetic racingsurfaces are susceptible to clumping as they contain significant fibrousmaterial and/or have constituents which can carry a static electricitycharge. It would be ideal to record or broadcast a horse race from theperspective of the jockey using a camera 90 on a goggle mount 300.

In a preferred embodiment, as depicted in FIG. 8-10, a video camera 90is mounted onto jockey goggles 285 to record or broadcast the event. Inthe present embodiment, the innermost set of goggles 285 is equippedwith a miniature camera 90 mounted on the nose bridge 263 of the goggles285, between the eyes of the wearer. The goggles 285 nested outside ofthe inner pair of goggles 285 each possess a transparent lens shield272. The lens shields 272 are arranged so that the adjacent underlyinglens shield 272 is protected by the adjacent outer lens shield 272.Preferably each lens shields 272 is constructed from the same materialas the goggles' lens 275. Common materials are polycarbonate, mid indexplastic and similar transparent materials. As one set of goggles 285 orits lens shield 272 becomes occluded, the jockey removes it mid-racedown around the neck in order to expose an underlying clean set ofgoggles 285 with a clean lens shield 272.

The lens shield 272 can be an extension of the goggle lens 275 or it canbe affixed to the nose bridge 263 on the goggles 285. The goggle lens275 and lens shield 272 have a consistent thickness to preventdistortion. The substantially transparent material for the lens shield272 and goggle lens 275 is chosen based on the desired refractive index,light absorption, and light dispersion, i.e. light scattering,properties. Additionally, a lens shield 272 and goggle lens 275 shouldpossess no manufacturing defects which could affect the wearer's visionor blur the image recorded by the camera 90.

The material for the lens shield 272 is determined in part based on theAbbe number. The Abbe number is used to describe the dispersionproperties of the lens 60 in relation its refractive index and is theratio of the angle of deflection to the mean dispersion angle. A highAbbe number indicates a low level of dispersion. A higher index ofrefraction means a denser material and therefore a thinner lens. In oneembodiment, the chosen lens material has inherent flexibility. In yetanother embodiment, the chosen lens material is rigid. Table 1 providesexamples of the optical properties of common lens materials.

In an alternative embodiment, a plurality of removable lens shields 272are affixed to the nose bridge 263 of a single pair of goggles 285. Eachlens shield 272 possesses a means for pulling 274 or peeling anindividual lens shield 272 away from the goggles 285. Such pulling means274 includes tabs and similar extensions spatially arranged to permitthe wearer to differentiate between the stacked lens shields 272 andwhich permit the wearer to grasp and individually remove the outermostlens shield 272. An adhesive is applied between the individual lensshields 272 in an area that won't be in front of the lens 60 so as toadhere each lens shield 272 to an adjacent lens shield 272 untilphysically removed by the wearer.

The audio-video cable 140 is affixed to and runs along the top rim 255of the goggles 285. A mini-DVR 200 is remotely worn by the user for datastorage. A microphone 137 is also worn by the user to capture audio torecord with the video data. In an alternate embodiment, the video andaudio data feed from the camera 90 is sent to a portable transmitter 189worn by the wearer for broadcast. In a preferred embodiment, the data istransmitted by Wi-Fi or cellular 3G or 4G technology. In a furtherpreferred embodiment, Wireless HD is used to transmit data by a wirelesstransmitter 189.

A preferred embodiment, as depicted in FIG. 14, incorporates a cameramount 130 designed to affix to the nose bridge 263 of a pair of glasses285 or safety goggles 285. The camera mount 130 would mount in front ofthe nose bridge 263 by using at least one arm to hook over the top ofthe bridge 265 while the bottom of the bridge 263 would possess at leastone arm which would engage the rear of the bridge 263 by passing belowthe base of the bridge 270 to engage the rear surface of the bridge 260or lenses 260. The mount 130 uses the bridge 263 as a fulcrum aboutwhich the mount 130 is affixed by first engaging the top 265 or base 270of the bridge 263 and then applying pressure about the bridge 263 toengage the remaining arm(s) of the mount 130. The converse constructionof the mount 130 is also workable with the mount passing between thebridge 263 and the wearer while engaging the outer surface of the bridge263 and/or lenses.

As depicted in FIGS. 7, 7 a, and 7 b, additional embodiments may usecamera mounts 130 in a variety of military and sporting helmets, e.g.football, hockey, lacrosse, and baseball helmets where the camera 90 isrecessed and mounted within the protective confines of the helmet 580but preferably outside of the wearer's field of vision, e.g. adjacent tothe forehead. In a further alternative embodiment, a helmet 580outfitted with a camera 90 would utilize a DVR 200 housed within thehelmet 580 or affixed thereto. Preferably the DVR 200 would be housedwithin the back of the helmet 580 to minimize damage from impact. TheDVR 200 may be secured within a DVR storage compartment 586 within thehelmet 580. Ideally, the inclusion of the DVR 200 is accomplishedwithout a reduction in the thickness of any padding within the helmet580. Alternatively, a mobile transmitter 189 could be integrated intothe helmet 580, e.g. in the DVR storage compartment 586, using the DVR200 to buffer the data feed or compress it prior to transmission. Thisdata would prove useful in evaluating conditions or performance formilitary and rescue personnel as well as providing feedback on athletetiming, attentiveness and readiness. A plurality of cameras 90 could beemployed to gauge team timing, effectiveness and communication.

When the camera 90 is mounted in a helmet 580, vibration and shockresistance are important thus the helmet mount 600 is anticipated to beconfigured with vibration dampening or deflecting materials and/orstructures. The helmet mount 600 is preferably affixed to the front ofthe helmet 580 and possesses a mounting flange 571, preferably mountedbetween the helmet padding 574 and the helmet inner surface 573. Thehelmet mount 580 is ideally recessed under the brim 575 of the helmet580 at the forehead to keep it out of the visual field of the wearer. Apreferred embodiment of a helmet mount 600 incorporates reinforcementribs 570 and arcuate support arms 572 with the apex of the curve of eachsupport arm 572 extending laterally relative to the mount'sproximal-distal axis. The reinforcement ribs 570 and support arms 572act to absorb vibration between the helmet mount 600 and the camera 90.The helmet mount 600 possesses mount fastener holes 584 which align withexisting fastener holes 590 in the helmet 580 so as to not affect thestructural strength of the helmet 580 and permit the mount flange 592 tobe mounted to the helmet 580 using fasteners 595, e.g. snaps, rivet, andbolts.

The support arms 572 fix the camera mount in place relative to thehelmet 580 and permit the helmet mount 600 to move proximally relativeto the helmet 580 as the helmet 580 is pressed against the forehead. Thesupport arms 572 also provide torsional flexibility, allowing the camera90 to move and deflect laterally as well providing limited rotation ifan outside object gets inside the facemask 582 and impacts the helmetmount 600, thus minimizing breakage and extending the life of the helmetmount 600. In a preferred embodiment, the helmet mount 600 make use ofrounded edges to minimize the likelihood that an outside object willcatch on the camera 90 or support arms 572.

The mount flange 571 ideally possesses at least one and preferably twoflange fastener holes 584 aligned with the helmet fastener holes 590 inthe front of the helmet 580. The flange fastener holes 584 arepreferably slotted so as to permit the mount flange 571 to be secured tomultiple helmet designs. The mount flange 571 may be held in place witha fastener 595. A flexible, positionable helmet mount 600 is preferred.The helmet flange 571 is preferably molded from a deformable materialsuch as a thermoplastic, e.g. acrylonitrile butadiene styrene (ABS).

In yet another embodiment depicted in FIGS. 11-12, a camera 90 iscoupled with a gun barrel mount 400 which is affixed to a gun barrel 380by an adjustable barrel band 350. Ideally a gun barrel camera mount 400would have vibration dampening properties. In alternative embodiments,the adjustable band 350 may be elastic band, a ring clamp, or a strap.This embodiment is anticipated to aid in target acquisition and shootingmechanics for hunters, police, soldiers, and sharpshooters.

An additional camera mount 130 embodiment incorporates a ball and socketjoint mount 500, as depicted in FIG. 15, to permit the camera 90 to berotated into a desired position. Ideally, the ball and socket joint 490is possesses sufficient friction across the joint 490 to permit the ball480 and socket 485 to maintain their relative positions.

In a further embodiment, as depicted in FIG. 16, a camera mount 130further comprises a means to attach the mount 130 to the bridge 263 of apair of glasses or goggles 285. In a preferred embodiment, at least onebridge clip 286 extends from the top of the camera module housing 70 topermit the bridge mount 290 to be removably mounted. Preferably, thebridge clip 286 is formed as an upwardly extending arm 591 progressingfrom the bridge clip 286 origin at the top of the camera module housing70, cresting at a distally oriented bend, and progressing down andforward toward the nose bridge to form a terminal point that creates aninverted u-shape.

The integrated data and power cable is preferably passed along the topof the glasses 285 or goggles 285, outside of the vision of the wearer.The cable may be integrated into the glasses 285 or goggles 285 or maybe affixed by attachment means, e.g. clips, glue, or similar means ofattachment. The clips 258 channel the cable along or impinge the cableto the frame of the glasses or goggles 285. The clips 258 are affixed tothe frame of the glasses 285 or goggles 285 either by clipping using atleast one tensioned arm 291 to create a friction fit arrangement or maybe securely attached to the frame by common means of attachment, e.g.adhesives, screws, hook or loop fabric, and bands which pass through theclip and around the frame. Ideally, the integrated data and power cable140 will pass around the head of the wearer via a helmet or head gearand down the back to a power supply and data recording media assembly250 and/or buffer. Within a jockey's helmet 280, the audio-visual cable140 can be installed so as to pass beneath the padding 282. Theaudio-visual cable 140 is run to a data recorder 250 affixed to thehelmet 280 or worn by the jockey. Alternatively, the data can bewirelessly transmitted from a wireless transmitter 189, e.g. transponder189, to a remote receiver 192. In a still further embodiment, a wired137 or wireless microphone 195 can be incorporated for the capture ofsound along with video or pictures.

In a preferred embodiment, cable clips 258 attach the audio-visual cable140 to the top rim of the goggles 255. The cable clips 258 are affixedso as to provide customized guidance of the audio-visual cable 140.

Fishery Management Application

As depicted by FIG. 17, the system comprises modular componentry forintegration with a control system 37. A modular miniature video camerasystem 25, i.e. camera/DVR module 25, comprising a miniature videocamera 10 (“camera”) and digital video recorder (“DVR”) 15 containedwithin a water-resistant housing 20 may be removably affixed at adesired location on a vessel, e.g. above deck and positioned to recordwhere the catch is brought on board, sorted, stowed, and, in some cases,returned to the water. The camera/DVR housing 20 accommodates the camera10, DVR 15, internal battery 31, and control panel 33.

The small size of the camera/DVR module 25 simplifies installation andincreases the available surface area on a vessel that can be utilized toaccommodate a mounted camera/DVR system 25. The camera/DVR housing 20 ispreferably removably affixed to vantage points about the vessel so thatit can be replaced or relocated if necessary. This resolves issuesconcerning blocked or malfunctioning cameras 10 by providing for anincreased field of recording from dispersed vantage points. The housing20 is waterproof to 1 meter so as to protect the camera/DVR 25 from theenvironment.

A camera/DVR 25 is preferably battery powered to facilitate the mountingof the device in locations where wired electricity may be problematic. Acamera/DVR system 25 may alternatively be powered by or have itsbatteries charged by the vessel's generator. In a still furtherembodiment, a camera/DVR system 25 may receive supplemental power bywind or solar.

The small size of the camera/DVR 25 permits the mounting of multiplecamera/DVR modules 25 at the same location, e.g. on the same mast,either side by side or one above the other so as to provide day andnight recording from essentially the same vantage point via two separatemodules that can be independently operated so as to switch over manuallyor based on trigger events such as light or time. This can also beuseful for the deployment of backup camera/DVR modules 25 or alternativecamera/DVR modules 25 feature differing lens or the specialty cameras 10such as low light, night vision, and thermal detection. In a usefulembodiment, deckhands can be outfitted with a wearable cameras anddigital video recorders to supplement the video record as needed.

In the event that a backup configuration is utilized, the data channelto the control system 37 can be switched either electronically ormechanically. The use of multiple camera/DVR modules 25 also extends theuseful life of the system 100 while at sea from a power consumptionperspective since one camera/DVR module 25 could be utilized during afirst time period and second camera/DVR module 25 utilized during asecond time period, and so on. In a further useful embodiment, deckhandscan be outfitted with a wearable camera/DVR module 25 to supplement thevideo record when necessary.

The mounted camera/DVR systems 25 records video to a computer readablemedia 27 which is removable for remote uploading to a data storagedevice 40. Alternatively, the data stored in the DVR 15 may be remotelyaccessed and downloaded to a central data storage system 40 that ispreferably sited at the bridge of the vessel. When a camera/DVR 25 isnetworked to the control unit 37 and remote data storage device 40, thecamera/DVR 25 stores data locally within the housing 20 to reduce therisk of data loss or corruption. In an embodiment, a control unit 37receives video data from the camera/DVR systems 25, with each video datastream being received across a distinct data channel 38 in the controlunit 37. The control unit 37 subsequently directs the received videodata to a central data storage system 40. Wired transmission of data toa shipboard central data storage system 40 is expected to employstandard data transmission techniques and components, or may utilizedata serialization and transmission techniques described and claimed bythis inventor in U.S. patent application Ser. No. 14/178,256.

The recorded video can be matched with time/date and location datavariables for verification of variables associated with the catch. Allor some of the time/date and location variables may be embedded into thecaptured video during recording, or they may be stored as a separatedata stream. Preferably the system 100 is coupled with a globalpositioning system (“GPS”) 45 to simultaneously record location data orembed it into the video data. The collected data is used to verify theprecise location, date, and time of the catch.

Data from other on-board sensors 39 may also be recorded usingadditional channels 38. Useful data would include, but would not belimited to net motor/drum actuation, hydraulic pump actuation, hydraulicpressure, air temperature, water temperature, hold temperature, changesin illumination, and motion. The availability of additional data sourcesfrom sensors 39 can be added in a plug and play fashion to the controlunit 37 so that unassigned data channels 38 allow each vessel to collectcustom, mission critical data as required by the fishery management planor the desire of the user.

The large range of selectable inputs facilitates the creation of controlalgorithms, i.e. software triggers, that can more accurately captureonly the desired imagery without capturing extended periods ofnon-activity that unnecessarily occupy valuable data storage and depletebattery power. Useful sensor data for software triggers include lightsensors, motion sensors, sound sensors, and sensors that indicate theoperation of mechanisms utilized to bring the catch on board, e.g.hydraulic pressure changes or motor/drum activation. The use of softwaretriggers reduces the amount of data that must be analyzed andsubstantially reduces the overall operational cost of the system whileincreasing its efficiency. For example, a catch deck observationcamera/DVR 25 can be actuated upon sensing the operation of the motor toreel in a net or by a change in the vessel's hydraulic fluid pressurecombined with motion on the catch deck. Camera/DVR 25 selection can betriggered by motion detectors 50.

In situations where a night vision camera/DVR 25 is mounted alongside adaylight camera/DVR 25, camera/DVR 25 selection between the two can beautomated by data from a photovoltaic cell. The system 100, in analternative embodiment, can generate a report on command that compilesimage, time/date, location, and sensor data into the report. Ideally,the recording field of the installed cameras 10 includes at least theentire deck area where the catch is handled.

The system 100 is capable of rapid installation and removal from anyvessel in a matter of minutes, and transfer to another vessel can evenoccur at sea. The camera/DVR module 25 is readily swappable with areplacement unit to facilitate maintenance while at sea, resulting intremendous cost savings. This also results in a significant cost savingsto the fleet because one system can be rapidly relocated to a sistervessel, even while both are at sea. The modular system is also smallenough that backup components can be purchased and stored on board tominimize down time and prevent returns to port which can be costly andcause significant reductions in the catch, especially in regards toshort seasons for migratory species.

The system 100 and its modular components can be installed in the fieldby an individual with minimal training in a matter of minutes. Thesystem 100, in its simplest form, is designed to work as a single uniton small vessels (<20 ft in length) or by chaining multiple unitstogether in a master and slave configuration to provide multiple cameraviews on larger boats (20-50 ft and larger). A command to initiaterecording on a master camera/DVR module 60 initiates recording on thechained slave camera/DVR modules 65.

In an embodiment of the system, the data is locked from editing toprevent tampering and ensure data integrity. Video data is transferredto the storage device 40 either locally or remotely. When data is storedlocally on a DVR 15 the data may be downloaded from that DVR 15 via aremovable computer readable memory 27, via an interface, e.g. USB port,or via a wired connection. The data is preferably relayed in real-timefrom a camera/DVR module to a protected data storage device 40. Wiredtransmission of data to a shipboard data storage device 40 is expectedto employ standard data transmission techniques and components, or mayutilize data serialization and transmission techniques described andclaimed by this inventor in U.S. patent application Ser. No. 14/178,256wherein a mounted camera/DVR module 25 is configured to serialize theparallel video data stream for simultaneous transmission over multipleleads to a data storage device 40 where is de-serialized prior tostorage. In an embodiment of the system, editor access to the datastorage device 40 is locked from editing to prevent tampering and ensuredata integrity.

Time and date data are intended to be continuously generated by thecontrol system 37 so as to indicate any downtime on the system 100 orits components. Preferably the central data storage system 40 has aredundant backup and independent power supply from that of the ship soas to prevent data loss. In an alternative embodiment, the data can alsobe streamed off-board via satellite while still at sea.

In an embodiment, morphometrics may utilized to generate a speciesdetermination and calculate various measurements via an analysis of thevideo data using an image recognition system such as an IntegratedPhoto-based Online Fish-Identification System (IPOFIS) exemplifyingInteractive Electronic Keys (IEKs). An IPOFIS is a photo-based onlinefish identification system that integrates three methods: visualinspection, dichotomous keys, and a multi-attribute query procedure.Each fish species is represented by multiple color photographs ofdifferent individuals and close-ups of important identificationfeatures. The system efficiently organizes and presents thesephotographs and associated morphometric information in an interactiveformat that facilitates fast and accurate identification. Stereophotogrammetry improves the results of the analysis because thethree-dimensional shape of the fish can be ascertained. The use of awearable camera/DVR module 25 improves the analysis further by providinga vantage point unobtainable from mounted camera/DVR modules 25 and canprovide images from numerous angles while the user is moving about thecatch. The internet offers a broad array of information and tools forthe identification of fishes by experts and non-experts.

Various internet resources can be of particular use for obtaininginformation on a species to populate a species identification database.FishBase, SeaLife Base, FAO FishFinder online publications and manyother (often local or regional) sites include descriptions of diagnosticcharacters and distribution maps as well as bioecological and fisherydata.

In a further embodiment, at least one camera/DVR 25 utilizes a highdefinition camera 10 with sufficient magnification and resolution topositively identify the species by an analysis of its scales. Fishscales have been extensively used in fish species identification sincethe early 1900s. Descriptions of their shape and particular featureshave long been used in to recognize families or distinguish betweenclose species. Moreover, alternative methods of shape analysis, based onlandmark data, have found wide applicability in biology because of thenatural links between homologies and measurements. Fish-scale shape isespecially useful for discrimination among genera, species and alsosympatric populations.

Using images acquired through stereo photogrammetry, algorithms cananalyze the image of the catch to determine the species caught, itslength, and its mass. Reference markings within the recording field ofthe camera 10 can provide validation data against which the focus andcalculations can be checked to improve the accuracy of the calculations.

Non-limiting examples of measurement variables which may be utilized areupper jaw to operculum, lower jaw to operculum, upper jaw to eye, headdepth, inter-orbital distance, upper penducle, lower penducle, upper jawto pre-operculum, fork width, gill spread, gill height, gill surfacearea, upper jaw to first gill, and upper jaw to last gill. Ratios ofcertain variables are also useful in achieving a better determination ofspecies and physical attributes. In a still further embodiment, othervisual variables can be input into algorithms, e.g. body striationmatching, patterns of coloration, the count and location of the fins,scale patterns, and the surface area of fins relative to the body size.

According to various embodiments, proprietary software applications orcommercially available software applications, e.g. Photomeasuremanufactured by SeaGIS Pty. Ltd. of Australia, may be utilized todetermine the length between two points on an image, which withparticular reference to the present disclosure, may be two points thatdefine a characteristic length of a fish shown as an object in ananalyzed image.

In various embodiments, the following equation from an NOAA technicalmemorandum may be used to convert the estimated total length of theidentified fish to mass in kilograms:In(W)=In(a)+b(In(L))where W is the mass (kg) and L is the total length (cm), and variables“a” and “b” are constants for that species. Similar statistical modelscan be constructed using the aforementioned variables that canaccurately estimate the mass of the fish. Averages over time can alsoprove beneficial in estimate the mass and quantity of the catch as well.

It should be appreciated that the relationship between length, mass, andvolume may vary from species to species, as well as on other factors,such as the time of year of the catch, the sex, and the geographiclocation. The algorithms take such factors into account to optimize theanalysis. A report summarizing the calculations may be generated andprovided to fishery management administration for review upon return toport or while still at sea should the vessel be intercepted.Alternatively, the data could be uploaded by a satellite link ortransmitted by radio.
